Assertion : The switch S shown in the fi...

Assertion : The switch `S` shown in the figure is closed at `t = 0`. Initial current flowing through battery is `(E)/(R + r)`
Reason : Initially capacitor was uncharged, so resistance offered by capacitor at `t = 0` is zero

A

Statement-1 is True,Statement-2 is True, Statement-2 is a correct explanation for Statement-1

B

Statement-1 is True,Statement-2 is True, Statement-2 is NOT a correct explanation for Statement-1

C

Statement -1 is True, Statement-2 is false.

D

Statement-1 is False, Statement-2 is True.

Text Solution

Verified by Experts

The correct Answer is:
A
Charge on capacitor `q=CE(1-e^(-t//CR_(eq)))`
`:. I=(dq)/(dt)=E/(R_(eq))e^(-t//CR)`
at `t=0,I=E/(R_(eq))=E/(R+r)implies` resistance offered by capacitor is zero,
